How To Install python-pretty-yaml on Ubuntu 18.04
Introduction
In this tutorial we learn how to install python-pretty-yaml on Ubuntu 18.04.
What is python-pretty-yaml
python-pretty-yaml is:
YAML is generally nice and easy format to read if it was written by humans. PyYAML can a do fairly decent job of making stuff readable. pyaml tries to improve on that a bit, with the following tweaks:
- Most human-friendly representation options in PyYAML get picked as defaults.
- Does not dump “null” values, if possible, replacing these with just empty strings, which have the same meaning but reduce visual clutter and are easier to edit.
- Dicts, sets, OrderedDicts, defaultdicts, namedtuples, etc are representable and get sorted on output (OrderedDicts and namedtuples keep their ordering), so that output would be as diff-friendly as possible, and not arbitrarily depend on Python internals.
- It appears that at least recent PyYAML versions also do such sorting for Python dicts.
- List items get indented, as they should be.
- bytestrings that can’t be auto-converted to unicode raise error, as yaml has no “binary bytes” (i.e. unix strings) type.
- Attempt is made to pick more readable string representation styles, depending on the value.
- “force_embed” option to avoid having &id stuff scattered all over the output (which might be beneficial in some cases, hence the option).
- “&id” anchors, if used, get labels from the keys they get attached to, not just use meaningless enumerators.
- “string_val_style” option to only apply to strings that are values, not keys.
- Has an option to add vertical spacing (empty lines) between keys on different depths, to make output much more seekable.
